+      Pdsh is a high-performance, parallel remote shell utility. It has
+      built-in, thread-safe clients for Berkeley and Kerberos V4 rsh and
+      can call SSH externally (though with reduced performance). Pdsh
+      uses a "sliding window" parallel algorithm to conserve socket
+      resources on the initiating node and to allow progress to continue
+      while timeouts occur on some connections.
